I hope someone can help. Before i start i will explain why..... my car runs, drives and idles fine but sometimes the engine seems growly and less responsive as though its running lean. I put a live data reader on it and noticed the maf readings are like 0.0 to 0.1 lbs/s at idle does go up to about no more that 0.9. One thing though. I dont have a maf i searched all over and i dont have one.so why am i getting teadings ???
